Valve Upgrades IMPROVE LIFE, EFFICIENCY AND CONTROL FLEXIBILITY


After many years of operation, steam chests and valves begin to suffer from end-of-life issues such as thermal cycling damage and the interaction of creep and fatigue. These problems may be compounded by demands for more flexible operation. Older valve technologies may also feature less than optimum flow paths and poor control precision.


GE has a wealth of experience in upgrading valves on many fleets and machine types. The most common way to achieve significant benefits is to upgrade the parts to improved, modern technologies. These can be adapted to the geometry, layout and interfacing systems of the unit under consideration. Our valve upgrades offer the following benefits:


• Lifetime extension • Efficiency improvement • Control improvement
